唇音字开合口的演变——从《韵镜》一系韵图到《韵法直图》一系韵图

The Evolution of the Opening and Closing of the Labial Words——From Yunjing System Rhyme Maps to Yunfazhitu System Rhyme Maps

从开合口的层面分析汉语语音的发展过程,可以从一个侧面来揭示汉语语音的发展规律。以唇音的角度,逐字探讨语音系统所发生的开合口变化,发现在韵部合并及声母的影响下,《韵镜》一系韵图唇音字中的非组三等凡韵合口字发展到《韵法直图》一系韵图时全部变成了开口字。

The study of the progress of the opened and closed syllables could help us to find the phonological regular patterns. The changes of the opened and closed syllables in the sound system were discussed word for word. We found the closed words of the third grade Fan （凡） rhyme in the Yunfing system rhyme maps had changed into opened words in the Yunfazhitu system rhyme maps because of the finals incorporation and the influence of the initials.
